Non-Obstructive Azoospermia and the Impact of MicroTESE.
Irish medical journal, 2016 In non-obstructive azoospermia (NOA), no spermatozoa are present in the ejaculate as a result of compromised or absent spermatogenesis. NOA is distinguished from obstructive azoospermia by patient history, clinical examination and hormone profile. As much as 10% of all male infertility has been attributed to NOA1. In contrast to obstructive azoospermia,
